tub of any of the well-known kinds now in use,

and shown in various Letters Patent, like that, for instance, shown in the patent to G. Schock, of June 1, 1880, of that shown in thepatent to S. E. Ohubbuck, of June 28, 1881, or in the patentto F. Fiederlein, of July '19, 1881. I merely cite these as illustrations of the kind of mash-tub in connection with which my improvement may be used, although, as above said, it is not limited to any particular construction of tub. I

Fig. 3 is a plan view of one of the heaters or stirrers. Fig. 4 is a plan view of the bottom stirren. Fig. 5- is an endview of the stirrer or beater shown in Fig. 3, and Fig. 6 is a side elevation of a mash-tub of any of the usual constructions in connection with which my improvements are used.

PATENT" OFFICE. 1'

In making my improvedfore masher to mix and moisten the'ground malt before admitting it intothe main mashing-tub I make an upright cylinder or circular chamber of boileriron, castiron, or -otherconvenient material,

and locate it immediately above the mash-tub. Q

I prefer to make two of these cylinders and place one over the mashtub toward each side, so that the malt when mixed and wet will be deposited'in two places on the floor of the 1 mash-tub, as in that way the work can be done more rapidly and easily. These cylinders,

pended or supported in the desired position in g 7 any convenient and suitable manner.

nected to the top of these cylinders should be the pipe or conveyer leading from the room or point where the ground malt is stored, so that e thesame may be carried, preferably by gravity, to the fore masher.

'power, so thatit may be revolved. I have not shown its connection with the motive power, I

I place an upright shaft in the center of this cylinder and connectit to as that can be effectedlby gearing, belts, or'in any of the other well-known ways.

stirrers or mixers D on the lowerportion of this shaft and key or fastenthem so that they will be caused to revolve with the shaft.

the drawings I have shown nut orset screws At the side of 9 This a on its lower portion. This shaft H is also con ne'cted by gearing or other suitable meansto lift the maltand carry it up to the top, where I I it will fall over into the mash-tub. v

The operation of my machine isas follows: Ground malt is admittedinto the pipe A and allowed to pass down into the cylinder B. The

ICO

shaft G in this cylinder isrevolved so as to re which I mark B in the drawings, may be 5115- as appropriate motive power, soas to revolve and I V volve the stirrers. Water is admitted through the pipe Ito mix with the ground malt. As the malt passes down it becomes thoroughly mixed and wetted with the water and forced by the bottom piece into the cylinder 0. It is then lifted up by the screw and carried to the top of the cylinder, which is open, whence it is allowed to drop into the mash-tub with the least quantity of water possible. If two or more of these fore mashers be employed, the malt will be dropped into the mash-tub in as many places. It will then be operated upon by the machinery in the mash-tub for stirring, mixing, and heating it in the way provided.

I am aware of the construction of mashtubs shown in English Patents No. 731 of 1883, No.'4,328 of 1875, No. 1,759 of 1858, No. 778 of 1861, and German Patent No. 1,121,0f 1877, and I do not claim such constructions.

What I consider as new, and desire to secure by Letters Patent, is
